Brain metastases, often originating from lung cancer, are diagnosed using CT and MRI scans. Treatment involves corticosteroids, radiation therapy (WBRT), surgery, or chemotherapy, with WBRT often preferred.

Area of Science:

  • Neurology
  • Oncology
  • Radiology

Background:

  • Brain metastases are a common complication of systemic cancer.
  • Pulmonary sources account for over 25% of autopsy-proven brain metastases.
  • Patients typically present with subacute, progressive focal and generalized neurological symptoms.

Purpose of the Study:

  • To outline current diagnostic and therapeutic strategies for brain metastases.
  • To review the utility of neuroimaging in managing brain metastases.
  • To discuss various treatment modalities and their associated risks and benefits.

Main Methods:

  • Review of current concepts in diagnosis and treatment.
  • Discussion of neuroimaging techniques (CT and MRI) for detection and monitoring.

  • Evaluation of treatment options including corticosteroids, WBRT, surgery, radiosurgery, and chemotherapy.

    • Main Results:

    • CT scans are often sufficient for diagnosis and monitoring.
    • MRI enhances detection of occult metastases, leptomeningeal disease, and complications.
    • Pulmonary origin is a frequent source of brain metastases.

    Conclusions:

    • Corticosteroids offer rapid symptom relief but have risks.
    • Whole-brain radiation therapy (WBRT) is a common treatment but carries complications.
    • Surgery for single metastases and WBRT after radiosurgery show promise; chemotherapy's role is unclear.
